Application filed November 16, 1917. Serial No. 202,434.

1 '0 all whom it may concern:

Be it known that I. ONNI WILLBERG, a

citizen of the United States, residing at' Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Stippling Apparatus, of which the following is a specification.

The principal object of my invention is to provide new and improved apparatus for producing a stippled finish on wall paper and other surfaces. Another object of my invention relates to a machine for applying color continuously to a movin strip 0 paper; in this connection I provi e apparatus for producing a stippled effect in the color after it is applied. All these objects and others will be made apparent in the following specification and claims taken in connection wlth the accompanying drawings in which I have shown'one specific embodiment' of my inventiombut it will be understood that various modifications can be made within the scope of the'invention.

Referring to the drawings, Figure 1 is a general side elevation of a machine for applying color-to paper with my stippling apparatus embodied therein.

Fig. 2 is a section on the line 2 of Fig. 1 showing the stippling apparatus, and

Fig. 3 is a top plan view of the parts which appear in elevation in Fig. 2.

The frame 11 carries a plain paper roll 12, from whichthe paper 13 passes around a drum 14. The trough 15 has water color 16 therein which is carried up on the surface of the drum 17 from which it is taken by the revolving brush 18 and applied by contact with the paper as it goes around the drum 14. The brush l9 reciprocates transversely distributing the color more evenly on the surface of the paper 13. The platform 20 has two rollers 21 and 22 at its ends and around them passes an endless band 23, on which the paper 13 moves forward under the idle brush 24 and two more transversely reciprocating brushes 25 and 26. The brush 25 has a much wider amplitude of movement than the brush 26 and the efpitmen 31 and 33 from the respective eccentrics 30 and 32 on the shaft 27, which is driven by the pulley 29 from the belt 28.

The brush 34 is supported on two blocks 35 with holes therethrough engaging the transverse rods 36 so that the brush 34 can reciprocate transversely to the paper by the sliding of these blocks 35 on the rods 36. These rods 36 are supported at the ends 37 on the upright slides 38 which are mounted to reciprocate vertically in the guides 39 and 40 carried by the frame 11. Each vertical slide 38 is engaged at 41 by a pitman 42 driven from a crank 43 at one.end of the shaft 44. This shaft 44 is driven from the .main belt '50 through the band wheel 49,

At its end the shaft 27 carries a sprocket wheel 51 from which the chain 52 goes to another sprocket wheel 53 carrying the crank pin 54, from which a bent pitman 55 extends to the point 56, where it has a flexible engagement with the brush 34. The tension spring 57 counter-balances part or all of the weight of the vertically reciprocating system comprising the brush 34, guide rods 36, vertical slides 38 and pitmen 42.

The rollers or drums shown in the drawings are all power driven except that the paper roll 12 is turned by the pulling of the paper 13 therefrom and the brush 24 is an idler.

As the paper 13 passes about the drum 24 it receives the water color somewhat irregularly from the brush 18. The transversely reciprocating brushes 19, 25 and 26 and the idle rotating brush 24, the brush 26 having a much narrower amplitude of movement than the other brushes, all serve to efi'ect a very even distribution of the color on the paper 13 at the point where it leaves the last of these brushes 26.

The brush 34 is jumped up and down rather rapidly striking down on the paper 13 approximately once for every inch of forward travel of the paper. Meanwhile, simultaneously, the brush 34 is reciprocated transversely to the direction of the paper movement on the rods 36. This transverse reciprocation of the brush 34 is eifected by the crank 54 carried by the. sprocket wheel. 105 53 and is 11 191! 1 Wer than the up and down movement, each complete cycle of the transverse movement of the brush 34 being accomplished as the paper advances about five inches so that there are about five up and down cycles of movement for each transverse cycle. The eifect is to produce a very evenly distributed stippling of the water color on the paper sheet 13.

After leaving the brush 34, the paper sheet 13 passes on to the right as viewed in Fig. 1 to a drier, where it is hung in festoons until the color is dry. Then it is gathered in rolls of measured length and is ready for use as wall paper or for wall decoration.

I claim 1. A machine for stippling paper comprising a' stippling implement, means -to guide the paper past said implement, and means to give the implement a movement to and from the paper-- and back and forth parallel to the plaper, these two movements being superpose 2. A machine for stipplingpaper comprising a stippling implement, means to guide the paper past said implement and means to give the implement a movement to and from the paper and superposed thereon a movement parallel to the aper.

3. A machine for stippling paper comprising a stippling implement, means to guide the paper past said implement in a direction lying in the plane of the paper and means to give the implement a movement to and from the paper and a superposed reciprocal movement parallel to the paper and transverse to the direction imposed by'said first mentioned 'means.

4. A machine for stippling paper, comprising means to guide the paper in a horizontal direction, a brush above the paper and means to strike the brush down upon the paper repeatedly and at the same time to give it a superposed horizontal movement.

5. In combination, means for applying color continuously to a moving sheet of paper, means for effecting an even distribution of the color, a stippling implement and means to strike said implement repeatedly against the paper with the color thereon and simultaneously to shift the implement in a direction parallel with the paper.

6. A machine for stippling paper compris-. ing a stippling implement, means to guide the paper past said. implement, means to give the implement a movement to and from the paper with a certain frequency, and means simultaneously to move the implement back and forth parallel to the paper with a less frequency.

7. A machine for stippling paper comprising a stippling implement, means to guide the paper past said/implement, means to give the implement a movement to and from the paper with a certain frequency, and means simultaneously to move the implement back and forth parallel to the paper with a frequency approximately one-fifth as great.

8. A machine for stippling wall paper comprising a brush, means to guide the paper past the brush and to give the brush a cycle of to and fro movement for approkimately each inch of travel of the paper and a cycle of back and forth movement parallel to the paper for approximately each five inches of travel thereof.
